|The files can only be stored in the '/tmp' directory.
The implementation attaches '/tmp' to the start of the
NMS specified file name. Therefore, if the NMS specifies
the file name as 'xyz', it'll be stored in '/tmp/xyz' and
if its 'xyz/pqr', it'll be stored in '/tmp/xyz/pqr'. But
if the name is '/tmp/xyz', the file will be created in
'/tmp/xyz' and not '/tmp/tmp/xyz'
